Application filed July 14, 190 Serial No. 216,560.

My invention relates to the locking mechanism of the doors of safes and vaults; and it has for its object to project the door-bolts into the door-jamb of the safe-body by means operated independently of the boltlocking mechanism.

Furthermore, as the means for projecting the door-bolts have necessarily to be operated from the exterior of the safe-door, my invention also has for its, object to construct and adapt my door-bolt-projecting mechanism in such wise that when it has been operated to project the bolts and the projecting mechanism has itself been locked by my locking mechanism all parts of my door-boltoperating mechanism will be rigidly and tightly wedged in place on its bearings, so as to preclude the leaving of a crevice between its abutting parts accessible from the exterior of the safe through which liquid explosive can be introduced into the interior of the safe for burglarious purposes.

Furthermore, it is one of the most important features of my invention that the door-bolt-projecting mechanism and also the locking mechanism of my safe is so contrived that the eflect of blows applied. to the outside of the door for the purpose of loosening the same and its bolt-operating mechanism instead of accomplishing such result shall, to the contrary, draw the door and its bolting mechanism the more securely to its bearings.

I accomplish my object by the construction and means hereinafter described.

In the drawings, Figure 1 is an elevation of my door locking from the rear, the rear plate 1' and collar 7' being removed to allow an inspection of the door-bolting and the locking verse central section of my door and a part of the door-jamb of the body of the safe. Fig. 3 is a transverse section of the shank c of the spindle c and the two-part threaded collar d on such shank. Fig. 4 is a partial rear elevation of the nut e. Fig. 5 is a cross-section Fig. 2is a partial vertical transsigned to receive a collar d, made of two of said nut on a line pointed by the arrow 90. Figs. 6 and 7 are respectively partial front and side elevations of one of said bolts. Fig. 8 is a cross-section of one of said bolts on a line y 11 of Figs. 6 and 7. Fig. 9 is a section on line y of Fig. 1. Fig. 10 is a partial crosssection of the door, showing the bolt 75 re placed by a bolt operated by a combination locking mechanism; and Fig. 1-1 is a partial interior view of the door, also showing the combination locking mechanism shown in preceding figure.

The letters and numerals designate the parts referred to throughout the description.

The body of my sale, or the jamb of thedoor if my invention is to be applied to a vault, will be made in an integral casting of that quality of steel known as unmachineable. It will be observed from Fig. 2 that the rim of the door and the faces of the doorjamb are made with a suitable taper, the abutting faces a I) being ground to each other. The door-jamb a is further made with four bolt-recesses (1 the outer wallsurface a of each of which recesses is tapered, so as to adapt the same to properly cooperate with the ends of the bolts, which have correspondingly-tapered surfaces, when such bolts are projected by the bolt-projecting mechanism provided for that purpose. The door 6 is made also in an integral casting of unmachineable metal. The door is provided in its center with a tapering cavity in which to rotatably hold a spindle 0, also made of unm achineable metal and having a corresponding taper, (see Fig. 2,) the bearingfaces of'said cavity in the door and the rim of the spindle 0 being ground to each other. The said parts are further made with a step or shoulder c to hold the spindle properly in place and to better ward off or resist blows which may be applied to the exterior of the spindle for the purpose of forcing the same inward.

The central part c of the spindle is made hexagonal in cross-section, and the inner end thereof 0 is also hexagonal, but of larger cross-section. Said center part c is departs (1 (1 as shown in Fig. 3, and provided with an exterior thread. On the collar (1 is a nut e. The nut 6 when rotated operates to project and retract the four bolts f. The rim of said nut is beveled and provided with four recesses 6, shown in the partial rear elevation of the same in Fig. 4, and the cross-section thereof, Fig. 5, taken on a line as of Fig 4.

The main portions or outer ends of the bolts f, as seen in Fig. 8, are cylindrical, while the inner ends of the bolts are made square and beveled at the base to conform to the bevel of the rim of the nut e. The opposite walls of the recesses e are made with inclined or oblique grooves 6 leaving projecting ribs 6 and the two lateral faces of the inner ends of the bolts f are also made with inclined grooves f and projecting ribs f, by which. construction the inner ends of the bolts f are adapted to be slidably seated in the recesses e of the nut. Of course more than four bolts may be employed in the combination of my locking mechanism; but the disposition of the bolts and the means foroperating the.

same would be substantially as shown and described. The bolts f are slidably held in apertures therefor made in the rim 1) and lugs g, the door being cast with cores g, of machineable metal, of which the lugs g are an integral part. are tapered to correspond and cooperate with the tapering wall portions a of the recesses a in the door-jamb.

On the hexagonal enlarged portion 0 of the spindle c is aflixed the hub or eye 72/, pro vided with a hexagonal opening of an arm h, having an inwardly-projecting lip-like portion h at its extremity. The arm his held in place by means of a plate 01, secured to the portion 6 of the spindle by means of a screwbolt 'i, the spindle portion 0 being cast with a core of machineable metal,.so as to provide for the tapping of the same to receive the screw t".

The back of the door is covered by a circular plate which is fixed in place by means of screws j. In order to accommodate the screws 7', the bolt-flange b of the door is cast with cores of machineable metal, so that the same may be tapped t. receive said bolts. The eye of the plate j is made with a brass collar 7' for the purpose of providing a bearing for the exterior shoulder h being a boss on the eye or hub of the arm h. The spindle c is made with an exterior rectangular recess 0 adapted to receive the crank by which to rotate the spindle and project and retract again the bolts The operation of locking my safe is as follows: Supposing the safe-door to be set in the doorejamb, but unlocked, upon the rotation of the spindle c to the right by a crank inserted in recess 0 the nut e is drawn outwardlythat is to say, toward the exterior of the door. The effect of such movement of the nut e is to project the bolts f radially,

- driving the outer ends of the same into the recesses a of the door-jamb. The rotation of the spindle c is continued as far as it will The outer ends of the bolts f further. During the projection of the bolts f their outer beveled ends climb the inclined wall portions a of the recesses a, and by this means the door-rim is forcibly and tightly drawn against its bearings in the door-jamb. The door of my safe fits perfectly tight in the jamb of the safe-body by reason the ground contacting faces a 'b. 1n the section Fig. 2 one of the boltsis shown projected into its recess a by the rotation of the spindle in the act of locking the safe, and it will be observed that the wedge-like locking ends of the respective bolts j may enter still further their recesses in the rim of the door-opening of the safe-body. Thus is provided against the door when closed becoming loose in its bearings or seat in the safe-body by reason of wear of the bolts, and the same means insure that the door when closed cannot be loosened by ramming or other violent attack either on the door or the spindle. Upon the bolts f having been projected, as mentioned, the arm 74', rotating with the spindle 0, will have assumed the position in which it is shown in Fig. 1that is, it will be so arranged that it may be locked by the projection of the bolt 7c against any movement in the unlocking direction. The bolt 7c is projected by the looking mechanism into a recess b therefor made in the bolt-flange b of the door. The fiange b is an integral part of the door, but cast with cores of machineable metal in which to make the recesses for the bolts f and 7c. The bolt 76 is seated in the lugs Z Z, which are-integral castings of machineable metal, on the interior face of the door. As shown in the drawings, the bolt 7c is projected by devices operated by an automatic look at, the arrangement being as follows: The bolt 7c is made with a transverse slot, in which enters the projecting member of the crank-arm m, which is pivoted at m The crank-arm m is connected with a second pivoted crank-arm m by means of a connecting-rod 0. The crank-arm m is pivota lly connected with the bolt n of the automatic lock n. To the door-bolt f is aflixed a projecting finger g, and the crankarm m is made with an edge m', which when the bolt n of the lock 'n is retracted will be arranged parallel to the face of the bolt j". When the door is open and the boltsf are in their retracted position and the lock n has been wound up, the edge m bears against the end of the finger g; but after closing the door and rotating the spindle c' to project the bolts the finger (1 would be moved out of its engagement with the crankarm m and the latter be free to be operated by the spring of the bolt n, and the move ment of the arm m would have the, effect of projecting the bolt 7c into its aperture b locking the arm h in place.

XXO

' automatic lock, causing the latter to operate (p indicates a time locking mechanism provi ed with the usual pivoted lever 39 and connecting-rod 29 connected with the arm n of the automatic-lock mechanism. The timelock must be wound up, so as to be set, in the first place, as usual, after which the automatic mechanism may be wound up. After locking the door of the safe as described it cannot again be opened until the expiration of the time to which the time-lock p has been adjusted. The hour set having arrived, the time-lock, through the medium of the lever 10 and rod 19 will operate the arm n of the and retract the bolt n, and therewith to move the crank-arm m and its connections, so as to retract the bolt 76, after which the spindle 0 may be rotated to the left for the purpose of retracting the door-bolts f and opening the door.

It will be observed from Fig. 1 that the bolt 7c has a long beveled surface W, and that the lug or bearing Z for said bolt is so positioned as to allow for some further projection of the latter. When the bolt 7c is projected to the extent shown in Fig. 1, the arm it has been rotated to the position it assumes after the bolts f have'been projected to lock the safe, and the bolt-actuating spindle 0 cannot be rotated any farther by the leverage which can be applied to such spindle in the act of locking the safe, as above described. It is the particular function of the bolt is to securely lock the arm h and therewith the spindle 0 against reverse rotation after the safe has been locked. Now it is apparent that if after looking the safe the door-spindle were forced around a trifle more the arm it would also be moved a trifle forwardly and then, unless such movement of the latter were taken up by wedging the arm in the advanced position to which it has been moved, more or less looseness would result in the locking mechanism, which may cause suflicient looseness in the bearing of the door against its casing as to admit the introduction of liquid explosive in a burglarious assault on my safe. With my mechanism such efiect is, however, rendered impossible, for any forced forward movement of the arm it would cause the springcontrolled bolt k to be projected a trifle more, and thus would wedge the arm it just as tightly as before.

As shown in Figs. 10 and 11, the bolt 7c, by which the arm h is locked or wedged in place, and the means above described for projecting said bolt k, may be replaced bya combination locking mechanism of the well-known type for example, a lock 11, provided with a bolt 76, a spindle 12, a dial 12 As well known, in locks of the construction referred to, a spring is provided arranged and adapted to bear against the bolt it after the same has been projected, so as to hold said bolt in place, and when using a lock of the type last de-.

scribed I make use of said spring member for the purpose of obtaining a continual pressure on the bolt 76 to take up any lost motion or looseness of the arm due to any attempted forced rotation of the spindle c after the safe has been looked, as above more fully described.
